I am trying to overload
=== on a custom type (as a workaround for https://discourse.julialang.org/t/surprising-struct-equality-test), but I get an error.
cannot add methods to a builtin function
Here is some code
struct T1 s::String end Base.:(==)(x::T1, y::T1) = x.s == y.s Base.:(===)(x::T1, y::T1) = x == s
Why is this forbidden?
